HMCAD1511 Evaluation Board

HMCAD1511 Evaluation Board

Product Detail

The HMCAD1520-EBZ (HMCAD1511-EBZ) supports the HMCAD1520 (HMCAD1511), a 12bit (8bit), 640MSPS (1GSPS) multi-channel analog-to-digital converter. The board uses LTM8078 switching regulator and ADM7154 LDO as its power supply and uses LTC6419 as an optional high-speed ADC driver. The board is designed to interface directly with FPGA development boards with FMC (Vita57.1) connector.

This reference design provides all of the support circuitry required to operate the ADC in its various modes and configurations. It is designed to interface directly with the EVAL-SDP-CH1Z data capture card, allowing users to download captured data for analysis. The device control and subsequent data analyses can now be done using the ACE software package.

AD-FMCXMWBR1-EBZ

FMC X-Microwave Compatible Level Translator and Power Supply Kit

FMC X-Microwave Compatible Level Translator and Power Supply Kit

Features and Benefits

  • FMC-compatible form factor
  • Powered from FMC connector with external supply possibility
  • Provides level translation and various supply values
  • Compatible with RaspberryPi X-MW controller 

Product Detail

The AD-FMCXMWBR1-EBZ is a level translator and power supply board, with FMC-compatible form factor. It is powered from the FMC connector, with the possibility to add an external supply, for application that require higher load currents. In this case, the external supply is prioritized. 

AD-FMCXMWBR1-EBZ allows multiple level translated digital communications paths between a controller/FPGA device and X-MW blocks. The module provides multiple supply voltages with high current capability, that can be used to bias the X-MW blocks or other IC’s in a prototype design.

APPLICATIONS

  • RF and Microwave designs
  • Voltage level translation
  • General-purpose software radios
  • Radar systems
  • Point to point communication systems
  • Multiple input/multiple output (MIMO) radios
  • Automated test equipment

LTM8078 Demo Board | 40V, 1.4A Dual Step -Down μModule Regulator

LTM8078 Demo Board | 40V, 1.4A Dual Step -Down μModule Regulator

Features and Benefits

Demonstration circuit 2777A is a dual step-down DC/DC switching converter featuring the LTM8078 μModule regulator. The demo board is designed to deliver dual 5V/1.4A and 3.3V/1.4A outputs from a 7V to 40V input. The Silent Switcher® architecture minimizes EMI while achieving high efficiency at frequencies up to 3MHz. The modes of operation (Burst Mode® operation or discontinuous mode/SYNC) are jumper selectable. Burst Mode operation improves efficiency at light loads. 

The LTM8078 is a fixed frequency PWM regulator with current mode control scheme. The switching frequency is set by an appropriate resistor (R11) from the RT pin to ground. The RUN pin (RUN terminal) can be used to set the LTM8078 in micropower shutdown mode. Output tracking and soft-start pins (TRSS1/TRSS2) allow user control of output voltage ramp rate during start-up. The power good output of each channel (PG1 or PG2 terminal) will be low when that channel’s output voltage is outside of the ±7.5% regulation window.

The LTM8078 data sheet gives a complete description of the operation and application information. The data sheet must be read in conjunction with this demo manual.
